To explore the mechanism of increased collagen deposition in scirrhous carcinoma of the stomach, an attempt was made to define the role of transforming growth factor beta 1 (TGF-beta 1), secreted from tumour cells, as a possible humoral factor which functions in a paracrine manner to stimulate the production of collagen in regional fibroblasts.(More)
Human gastric carcinomas were tested for their immunohistochemical reactivity with anti-type I procollagen antiserum. In all specimens of scirrhous carcinomas, staining of the tumour cells was strongly positive, while in medullary carcinomas staining of the tumour cells was generally poor. These results suggest that the tumour cells in scirrhous carcinomas(More)
Aegilops triuncialis L. (2n = 4x = 28, genome formula UUCC) has been used to obtain one of the “Arsenal collection”, the distant hybridization of Triticum aestivum L. The introgression line 124/00i, which was derived from the cross of T. aestivum ‘Rodina' with γ-irradiated pollen of an accession of Ae. triuncialis. However, undesirable genes can be(More)
The “Gumbai” wheat landraces of are a distinctive group of Japanese common wheat landraces. They originated in the Yamanashi region of Japan and are characterized by compact spikes, which were called “Gumbai” in the Japanese language. It is well known that the spikes of club wheat (Triticum compactum Host, 2n = 6x = 42, BBAADD genome) are governed by the(More)
In the wheat (Triticum aestivum L.) inflorescence, spikelets are arranged in two opposite rows on the main axis. Spikelet primordia initiate alternately on opposite sides at angles of 180°. Genotypes exhibiting screwed spike rachis (SCR) have been selected as a gene resource having non-standard spike morphology in wheat. Although the SCR phenotype is a(More)
Plant height is one of the most important traits of wheat because it influences lodging resistance, harvest index and yield. Reduced height of wheat is achieved mainly by the introduction of Rht-B1b (Rht1), Rht-B1e (Rht11) or Rht-D1b (Rht2) dwarfing genes, which produce mutant DELLA proteins that constitutively restrain plant growth irrespective of(More)
Mutant genes conferring triple glume and ligulelessness were mapped in Aegilops tauschii (Coss.) Schmal. (2n = 2x = 14, DD genome), the D genome donor to common wheat (Triticum aestivum L., 2n = 6x = 42, BBAADD genome) using microsatellite probes. The trg (tr iple g lume) locus was linked (21.6 cM) with the Br t (B rittle r achis in Ae. tauschii) locus in(More)
The growth of the leaf blade is one of the limiting factors of the life cycle of a plant. The leaf elongation rate in early plant growth stages is important for plant establishment. The rlb (reduction of leaf blade) mutation in Triticum aestivum L. (2n = 6x = 42, BBAADD genome) caused a severe interruption of leaf blade development, a reduction of spike(More)
The liguleless phenotype in wheat lacks ligules and auricles on all plant leaves. Two duplicate dominant genes (Lg 1 and Lg 3 ) principally control the presence of ligules in tetraploid wheat. Although the Lg 3 gene was tentatively located in chromosome 2A, a genetic stock of Triticum durum Desf. (2n = 4x = 28, BBAA genome) having genotype lg 1 lg 1 Lg 3 Lg(More)
